Can I make a melee infiltrator?

From what I understand everything is supposed to be possible. Viable on the other hand...Still it's not like Bioware games are so overturned that you have to min/max everything to optimum efficiency to even stand a chance.

Should work. I'd go Cloak+Energy Drain+Flamethrower for active powers. Plus all the various melee boosting passives.

At higher levels, a Cloak vanguard might be the better option for melee, since they get a whole bunch of melee boosts. At lower levels limited skill points seem like it would be a problem for that, though.

Yeah I know about Vanguard, did that in ME2/ME3. Amazingly OP and fun.

But that is a completely different play-style and powers from Melee Infiltrator. I don't want Charge, I wanna sneak behind and stab for massive damage.

I guess I'll find out when it comes out.

That's really lame. Even ME3 wasn't like that unless you were playing solo.

You can quite easily I think but infiltrator does not seem to best the best profile for the job.
1° Vanguard
2° Soldier
2° (edit) Explorer
3° Infiltrator
4° Sentinel

Going vanguard give a big bonus to melee damage, excellent shields and doesn't require you to use any biotic power at all. However going Vanguard means you have biotic jump and evade so it's hard to pretend you are an infiltrator. If you don't care go for it. more info here
bsn.boards.net/thread/5552/specific-crazy-builds
Going soldier allow you to have stronger passive like melee damage, health and resistance
Going infiltrator don't add many thing. Your cd will already be low so you don't need to improve that. Maybe for ice/fire combo ? not great in theory
Going Sentinel add some resistance but remove a lot of the melee bonus, might not be viable at all

Tactical cloak melee build don't require any active ability except TC. and seems possible to play on the hardest ability, especialy with the combat improved aerial melee attack who give a bit of aoe.
If you look for pure viability I would go for vanguard with no need for biotic ability, except you will need to invest some point in the trees to improve the passives and the vanguard profile. Soldier is still strong but will have a harder time on melee, energy drain would be a good addition, especially against those flying drones.

Edit : Explorer is a compromise for vanguard. If you invest point in tech tree for energy drain level 6 and don't want to lose skill point in biotic tree just to increase the vanguard bonus profile explorer is a good deal. You lose a bit in melee damage, but you keep up in term of defense and more non-biotic friendly if that is your thing.

TC is very very strong and with stronger melee attack and melee aoe you will do wonders.
If you go that route I would take TC, Flamethrower and energy drain.
Flamethrower prime enemy and do bonus damage to armored enemy (hard to manage with melee weapon).
Energy drain would detonate them and allow you to fight flying drones.

Of course TC builds involve low cd and multiclassing to get all the bonus. The perfect candidate for several profiles.

Not the only melee profile.
Vanguard is good because
-profile bonus
-combat passive
-biotic shield
However it is a bit a lackluster when it comes to active abilities. To continue to up your profile you have to waste skill point in the biotic tree, someone going full soldier would increase further his passives. Moreover the vanguard bonus is great but not gamebreaking. TC does up your damage by 110% a 20% melee damage is not huge.

All thing considered Vanguard seems to be the best for melee combat, but is not the only spec able to do it. At first sure the bonus are huge for melee play style but later in the game you will probably waste point in biotic first and then combat. Still think it will be the best but combat and explorer will be close second.

Siphoning strike is good but not that good. Unless a melee attack result in instant full shield it doesn't change much to the fact you get shredded.
And there are multiple way to increase your defense. TC is one,  Combat fitness provide some huge damage reduction when health is low, Barrier gives you free shield every 10 sec when health is low. Energy drain can fully recharge your shield, Backlash for quasi-immunity...Combine some of them and you have a potent melee character. The explorer profile give straight damage reduction.

On higher level my pathfinder profile will give high resistance :
-Limited shield bonus from Barrier
-Health bonus from Combat Fitness
-Whatever bonus from armor
-Damage reduction from explorer profile
-Shorter tech cd from explorer profile
-Emergency escape from TC
-Emergency auto full shield from Barrier (with a 10 sec cd)
-Emergency full shield from Energy drain
-Emergency auto armor from Combat fitness
-Emergency invulnerability from Backlash
-Bonus shield after backlash

I don't feel like I'm defenseless. And it is not a 20% shield on a 1sec animation melee strike that will make the difference. I just have to survive 10 second for my Barrier special skill to be up again and if I drop Backlash I can still detonate combo and have anti-shield and flying drone solution. I don't think it is the best build but clearly it is viable.

Charge seems a much safer bet since it also recharges shields and it allows you to quickly jump in and use TC after it and follow up with a melee combo on lone enemies, or you can use it as an emergency heal. Barrier is also great for survivability.

1,2) Isn't the damage part of drain very low?
3) If you use cloak to engage you can use charge to engage on the next enemy, if you use charge you can use cloak to engage on the next enemy. I don't get what you are saying.
4) What do you mean and why would you use charge in melee?
5) It can be evolved to give full shields.
6) That's true.

I was just wondering what exactly was your thought process. Also why wouldn't you charge the remnants?
